Tests display the new 12V GPU electricity cables are safe while not completely related

Why it matters: The sixteen-pin 12VHPWR power cables for Nvidia's recent pics cards were controversial in view that customers started out reporting melting adapter plugs past due remaining year. The organisation quietly upgraded to a brand new specification this summer time, and current exams advocate the brand new widespread is drastically more secure.

HardwareBusters and energy cable manufacturer Linwell currently posted wonderful safety take a look at consequences for the brand new 12V-2x6 headers which can be now fashionable in Nvidia RTX 4000 images cards. Users involved approximately burning or melting cables need to be in particular thrilled to examine that the up to date connectors are secure even if improperly attached.

The Peripheral Component Interconnect Special Interest Group (PCI-SIG) released the new specification in July after dozens of RTX 4090 proprietors complained that the GPU's 16-pin 12VHPWR electricity connectors melted or burned after a few months. Nvidia's investigation blamed the problem on users who failed to securely join their cables, but others suspected poorly synthetic adapters. In any case, the pictures card corporation switched to the 12V-2x6 revision soon after its advent.

HardwareBusters confirmed Linwell – which components electricity cables for Asus hardware – testing the new general under 55 Amps for round 15 minutes. Thermal scanners constantly measured the connector's temperatures below 46 tiers Celsius throughout the trial.

Linwell then ran a 2nd test after deliberately bending the cables and improperly connecting them to copy the situations Nvidia suspects damaged many RTX 4090s. Still, the temperature remained beneath forty one degrees, nowhere close to hot enough to burn or melt. HardwareBusters credit the brand new, more conductive pins with minimizing resistance, even under high electricity hundreds.

So some distance, customers haven't pronounced damaged 12V-2x6 plugs, so that they appear safer than the original RTX 4000 series connectors. Customers looking for Ada Lovelace GPUs should confirm that they have the H marker on the top of the power connector in preference to the old H identifier.

Users with legacy fashions who can't afford to exchange their cards should transfer to ATX 3.0 strength resources instead of the usage of adapters to connect 16-pin 12VHPWR plugs into ATX 2.Zero PSUs. The newer PSUs may be more expensive, however they are less costly than probably changing a damaged GPU.

Meanwhile, AMD's state-of-the-art RDNA 3 graphics cards don't use 12VHPWR – a difference the company has used to poke amusing at Team Green. However, Asus might get the closing snigger because it considers forsaking photos card electricity cables altogether after demonstrating a GPU design proposing a PCIe power connector that could deliver at least 600W. Cableless RTX 4070 revisions, which require new motherboards, ought to start delivery either overdue this year or in early 2024.
